🎨 Message Variations (NEW in v2.1!)

One of the most powerful features to ensure high delivery rates and avoid spam detection!

Why Use Variations?

Without variations, sending identical messages triggers WhatsApp's spam detection:

  • ❌ 100 identical messages = High spam risk
  • ❌ Account may get banned
  • ❌ Messages flagged as spam

With variations, every message is unique:

  • ✅ 100 unique messages = Low spam risk
  • ✅ Better deliverability
  • ✅ Higher success rate (+10%)

5 Variation Modes

Mode 1: No Variation

Original message sent as-is. Use for testing or personal messages.

Mode 2: Random Suffix (Legacy)

Adds random text at the end. Backward compatible with v1.0.

Message

a8f3k2j9

Mode 3: Emoji Variation

Adds random emoji from pool of 12 emojis.

😊 Your message here
Your message here 👍

Mode 4: Whitespace Variation

Subtle spacing differences for unique message hash.

Mode 5: Full Variation ⭐ RECOMMENDED

Combines all features for maximum uniqueness!

Spintax Syntax

Use {option1|option2|option3} for word variations:

Example:

{Halo|Hi|Hai} {name}!

{Promo|Diskon|Sale} {spesial|khusus|istimewa} untuk Anda!

{Buruan|Segera|Cepat} order sebelum {habis|kehabisan}!

Result: Each message uses random selections, creating unique combinations!

Dynamic Variables

Auto-replaced with current values:

Variable Output Example
{date} 08/11/2024
{time} 14:30
{datetime} 08/11/2024 14:30
{day} Jumat
{month} November
{year} 2024
{random_number} 742
{random_string} A8F3K9

Example:

Halo {name}!

Promo spesial tanggal {date}!
Kode: {random_string}
Berlaku sampai akhir {month}.

2024-01-15 10:30:55 [error]: Failed to send message to 6281234567891

🔒 Security & Privacy

  • ⚠️ Never share your session files (.wwebjs_auth directory)
  • ⚠️ Keep your .env file private
  • ⚠️ Don't commit sensitive data to version control
  • ⚠️ Use at your own risk - WhatsApp may ban accounts for spam

🐛 Troubleshooting

QR Code doesn't appear

  • Make sure Chrome/Chromium is installed
  • Check if port 8080 is available
  • Try setting HEADLESS_MODE=false in .env

Messages fail to send

  • Check internet connection
  • Verify phone numbers are in correct format (with country code)
  • Ensure numbers are registered on WhatsApp
  • Check if you're not sending too fast (increase delay to 4-5 seconds)
  • Use sleep intervals for large blasts

Authentication fails

  • Delete .wwebjs_auth directory
  • Restart the application
  • Scan QR code again

Session expires

  • This is normal after long periods of inactivity
  • Just scan the QR code again when prompted

Spintax not working (v2.1+)

  • Check syntax: use {opt1|opt2} not (opt1|opt2)
  • No spaces inside: {a|b} not { a | b }
  • Ensure variation mode is enabled (not Mode 1)

Variables not replaced (v2.1+)

  • Use exact variable names: {date} not {Date}
  • Check dynamic vars are enabled in variation mode
  • See MESSAGE_VARIATIONS_GUIDE.md for supported variables

Messages still too similar (v2.1+)

  • Use Mode 5 (Full Variation) instead of Mode 1-4
  • Add more spintax options in template (3-5 per placeholder)
  • Combine spintax with dynamic variables
  • Enable emoji variation

📈 Best Practices

Message Safety

  1. Start Small: Test with a small number list first (5-10 numbers)
  2. Use Adequate Delays: Minimum 3-5 seconds between messages
  3. Add Sleep Intervals: Take breaks during large blasts (every 30-50 messages)
  4. Monitor Logs: Check logs regularly for issues
  5. Backup Sessions: Keep backup of .wwebjs_auth if needed
  6. Respect Privacy: Only send messages to people who opted in

Optimal Settings for Safety

For New Accounts (<3 months):

DEFAULT_DELAY=5000              # 5 seconds
Sleep after: 20 messages
Sleep duration: 90000           # 1.5 minutes
Daily limit: 200-300 messages

For Normal Accounts (3-12 months):

DEFAULT_DELAY=4000              # 4 seconds
Sleep after: 30 messages
Sleep duration: 60000           # 1 minute
Daily limit: 500-800 messages

For Established Accounts (>1 year):

DEFAULT_DELAY=3000              # 3 seconds
Sleep after: 50 messages
Sleep duration: 60000           # 1 minute
Daily limit: 1000-2000 messages

Message Variations Best Practices (v2.1+)

  1. Always Use Variations for Large Blasts: Mode 5 (Full Variation) for >100 messages
  2. Use Spintax Wisely: 3-5 options per placeholder, use synonyms
  3. Combine Features: Spintax + Dynamic variables = Maximum uniqueness
  4. Test First: Send to yourself 5-10 times to verify variations work
  5. Don't Overdo: Too many options (10+) makes templates hard to maintain

Recommended Spintax Patterns:

Greetings: {Halo|Hi|Hai}
Actions: {Buruan|Segera|Cepat}
Products: {promo|diskon|sale}
CTA: {order|pesan|beli}

Good Template Structure:

{greeting} {name}!

{action} {verb} {product} {adjective}!
Code: {random_string}
Valid: {date}

{cta_action} {cta_verb}!

{closing},
{sender}
